Untangle Server v7.1.0

I just installed an Untangle Server in router mode in our network but I am having a problem. I have multiple subnets, 192 and 172. The UT server is on the 192 network. All the clients on that network can get to the Internet but clients on the 172 networks can not. I can ping the interface on the 192 network and I can ping from the 192 to the 172 and vice versa. However, I can not ping the UT interface from the 172 network. Everything was working fine with the old router so I know it is something in the UT server. Any help would be greatly appreciated.
